Work out ink coverage instantly with clear inputs, formula shown and shareable results.
Ink per page is the sheet area times the coverage fraction times the ink laydown rate at full coverage, so pages per cartridge is the cartridge volume over that figure. Coverage can exceed 100% when several inks overlap, which is why a rich black photo page can drain a cartridge in a fraction of its rated life.
Ink per page
ml = sheet area m2 x coverage fraction x ml per m2 at full coverage
Cartridge yield
pages = cartridge volume / ink per page
ml = sheet area m2 x coverage fraction x ml per m2 at full coverage. Ink per page is the sheet area times the coverage fraction times the ink laydown rate at full coverage, so pages per cartridge is the cartridge volume over that figure.
Coverage can exceed 100% when several inks overlap, which is why a rich black photo page can drain a cartridge in a fraction of its rated life.
Enter ink coverage on the page, sheet area, ink used at full coverage, cartridge volume. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
